Tambalan saya lepas.

Tambalan comes from the root tambal, which has to do with patching or repairing something. As a noun, tambalan can mean a patch, repair patch, or filling.

So depending on context, Tambalan saya lepas could refer to:

• a dental filling
• a patch on clothing or an object
• some other kind of repair material that has come off

If the context is specifically dental, people often say tambalan gigi saya lepas for extra clarity.

In Indonesian, possession is usually expressed with the pattern:

noun + possessor

So:

• tambalan saya = my filling / my patch
• literally: filling of mine

This is the normal way to say possession. English uses my before the noun, but Indonesian usually puts saya after the noun.

The suffix -an often turns a root into a noun. Here:

• tambal = to patch, mend
• tambalan = a patch, a filling, something used as a repair

So tambalan is not the action of patching, but the result or object involved in the patching.

Here lepas functions as the predicate and means something like loose, detached, or come off.

Indonesian often allows words like this to act like the main predicate of a sentence without needing a verb like to be. So:

• Tambalan saya lepas = My filling came off / My patch came off

Depending on context, you can think of lepas here as describing the state of the filling, or as expressing the event that it came off.

Indonesian does not require a verb like to be in many simple sentences, and it often leaves tense unstated unless the context makes it necessary.

So Tambalan saya lepas can naturally cover ideas like:

• My filling is loose
• My filling has come off
• My filling came off

The exact English translation depends on context. Indonesian commonly leaves that kind of time information to the situation, or adds words like:

• sudah = already
• tadi = earlier
• baru saja = just

For example:

• Tambalan saya sudah lepas. = My filling has already come off.

Usually, no. It normally means the filling or patch came off, became detached, or is loose.

If you want to say I removed my filling/patch, you would use an active verb such as:

• Saya melepas tambalan saya. = I removed my patch/filling.

So the original sentence focuses on the state/event of becoming detached, not on the speaker intentionally taking it off.

Yes. Terlepas is also very natural and often sounds a bit more explicit for came off accidentally or became detached.

Compare:

• Tambalan saya lepas. = My filling/patch came off / is loose.
• Tambalan saya terlepas. = My filling/patch became detached / came off.

In everyday speech, lepas is common and simple. Terlepas can sound a little more formal or a little more clearly event-focused.

They are similar, but not identical.

• lepas is broad and neutral: loose, detached, come off
• copot often strongly suggests something has popped off, fallen out, or come out of its place

For a dental filling, many speakers would also say:

• Tambalan saya copot.

That is very natural in conversation. In some contexts, copot can sound a bit more colloquial and vivid than lepas.

Yes, it is a complete and natural Indonesian sentence.

Its structure is:

• Tambalan saya = subject
• lepas = predicate

Indonesian does not need an article like the/a, and it often does not need a linking verb like is. So short sentences like this are very normal.

If you specifically mean a dental filling, then yes, Tambalan gigi saya lepas is clearer.

Compare:

• Tambalan saya lepas. = My patch/filling came off.
• Tambalan gigi saya lepas. = My dental filling came off.

The shorter sentence is fine when the context already makes it obvious what kind of tambalan you mean.

Yes, if the situation is informal.

• Tambalan saya lepas. = neutral / polite
• Tambalanku lepas. = informal, natural in conversation
• Tambalan aku lepas. = possible in some informal speech, but tambalanku lepas is usually more natural

So in casual speech, a native speaker might often use the suffix -ku:

• Tambalanku lepas.

You can add time or aspect words.

Examples:

• Tambalan saya sudah lepas. = My filling has already come off.
• Tambalan saya tadi lepas. = My filling came off earlier.
• Tambalan saya baru saja lepas. = My filling just came off.
• Tambalan gigi saya lepas nih. = My filling came off, you know / just now.
  (nih is conversational.)

These additions are optional, but they help when you want to be more specific.
